6 Claims.

This invention` relates to shoe soling machines and has reference to such machines particularly adapted for cementing half soles and the like upon shoes in need of repair, although it is to 5 be understood that the same, lor portions thereof,

may be used in connection with the manufacture of shoes.

The principal object of the invention is to produce a more practical and convenient mech- 10 anism of this type than heretofore known.

Other objects and advantages of the invention will appear in the following description thereof.

Referring now to the accompanying drawings,

15 forming part of this application, and wherein like reference characters indicate like parts:

Figure 1 is a central vertical section, partly in elevation, and longitudinally of the shoe holding form of the assembled shoe press.

Fig. 2 is an enlarged perspective View of the adjustable shoe jack.

Figure 3 is a combined vertical section and elevation of the device; the sectional portion beingtaken centrally of the pivotal support of the 25 yoke.

Figure 4 is a bottom plan view of the adjustable jack.

Figure 5 is a perspective View of one of the jack toes. 30 Figure 6 is a top perspective view of Figure 5.

Figure 7 is a perspective view of the removable shank support.

It is well known in the art that the attachment of half soles or the like to worn shoes by 35 cement is common practice and that presses or similar devices are used for such purpose. Also that such devices are usually assembled in pairs corresponding to the right and left shoes of a pair, and in the disclosure of the present inven- 40 tion it is deemed sufficient to illustrate but a single one of the devices of such a pair.

In the accompanying drawings I represents a metal base of any desired form, though preferably provided with a single leg like support 2 at the front thereof and two similar side members 3 at the rear portion of either side, the top of the bas-eportion, illustrated at 4, being solid throughout, substantially rectangular in form, and having fixed transverse its rearmost upper face the rocker beam 5, having an upright guard 6 at either end for guidance of the shank carriage 1, while at the forward end of the base portion and centrally thereof extends upwardly the pillar 8 55 which rockably carries upon the shaft 9 transversely of the same the forward end of the shoe carriage IIJ.

The rearmost end of the shoe carriage I is supported normally in substantially parallel relation with the top of the base by the two transversely spaced expansive helical springs I I, while upon either side of the rearmost portion of the carriage is formed rearwardly and downwardly extending lugs I2 through which short pins or bolts extend inwardly for the pivotal support of the shank o-r tail carriage, it having depending lugs I3 similar to the lugs I2 and adjoining same for such pivotal support so that at this connection the complete shoe carriage is divided transversely, and free to move vertically with the shank carriage rocking upon the upper forward corner of the beam with the front end freely pivotal on the pin 9.

Into the shank carriage 1 is removably fitted the wedge shaped shank or instep supporting member I4 of which there may be a number of different shapes and forms applicable to the press for different classes of work; the shank carriage being provided with suitable side walls I5 and end wall I6 of the convenient holding of the auxiliary shank supports of various forms, as just described.

The adjustable jack or last for insertion within a shoe when the sole is being applied to same within the press comprises the gooseneck shank II terminating in its upper end in the normally parallel fiat topped head I8 for reception of the press screw, and at its lower end pivotally attached as at I9 to the adjustable last member comprising the elements 20 and 2|. These latter tread elements will subsequently be referred to as major and minor; the major one 20 extending rearwardly somewhat and being bifurcated, forming bearing lugs 22 and 23 for reception oi' the through pin 24 which pivotally supports within said bifurcated portion the projection 25 of the arcuately shaped shoe shank tread 26. This shank tread 26 carries pivotally as at 2'I the thumb dog 28 which is biased to forward position as by a suitable expansive spring 29 under the tail 30 of the dog, the opposite or head end of the dog being selectively engageable within any of the notches in the arcuate upstanding ratchet 3| xed as by the screws 32 to the top of the major element 20 of the tread portion; this being to permit of pivotal adjustment of the shank tread 26 to accommodate shoes having different shaped insteps or Shanks.

There is also shown formed integral with the shank tread 26 a pair o-f forwardly extending guides illustrated at 33 intermediate of which the head 28 of the dog operates, though these may be dispensed with if preferred.

It is to be noted that the minor section 2| of the shoe jack is adjustably mounted upon the pivotal support i9 of the jack shank and is pivotally movable independently of said shank and also of the major tread portion 2i), and that the shank of the jack is independently pivotally movable in respect to either of the tread portions 20 or 2 I, such independent movement of the parts being for the convenient reception of the removable tips or toe portions 34 of the jack or last.

It is apparent that the adjustable tip portion is for the provision of accommodating the last to different sized shoes and that changing of the tip only7 will accomplish such purpose. In the drawings I have shown as assembled in the last the smallest one of a set of tips, while in Figures 5 and 6 is shown the opposite sides of what might be termed the largest one of a set of say seven different tips. As is apparent the curvature of the marginal edges of the last and tip are thus made to coincide in each instance.

It will be noted that a series of depressions 35 are formed in the upper face of the head of the jackshank for selective reception of the press screw 36 which is preferably somewhat pointed, as illustrated, for fitting same, so that for diierent sized shoes selection as to convenient application of the members may be accomplished. The

press screw is vertically adjustable within the transverse portion 37 of the yoke 38, pivotally mounted upon the through bolt or shaft 39 in the depending walls 3 of the base of the press, this pivotal action of the yoke being also for further convenient accommodation and adjustment of the press to different sizes of shoes. The screw 36 is illustratedas being operated by a suitably shaped hand wheel 40 as is common in such devices, and the pitch of the screw being ne, together with having ample bearing in the hub portion 4| of the yoke there is provided convenient means for raising and lowering the screw quickly and eciently.

In the use of the device in cementing soles to shoes it is intended that a suitable pad 42, such as of sponge rubber, is fitted within the carriages I I3 and 'l before the job is applied thereto, thereby to insure close tting of the new sole to the shoe, and to compensate for any irregularity in either of the parts to be united.

It is deemed that the operation of the device is obvious except that it may be pointed out that when a shoe and sole to be applied is put into the machine with the last in place and the press screw applied with pressure, the tail or shank carriagefiy immediately comes to place in applying uniform pressure throughout the shank of the shoe; this occurring by virtue of the pivotal connection of the two carriage members previously described, and which action insures a smooth and uniform union not only of the two shank members being united, but in the event of what is commonly called a half solle with a seam transverse the shank being applied, a positive and smooth union is also assured.

It will be noted that each of the tips is provided on its upper side with a short section of ridge or tongue 43 which is designed to register with a similarly shaped groove 44 in the beak of the shank Vi so as to insure positive alignment of the point with the shank.

As a means for securely holding the tip or toe member 34 in position I have illustrated the meeting edges of the tip with the members 20 and 2f as being materially inclined as at 45, and provided also a spring controlled ball 4t in a suitably plugged hole directly above the central tapered portion of the tips when in position within the jack, each tip being provided with a slight depression or hole as indicated at 41 for snap engagement with the ball 46 when in position.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1.` In a shoe sole cementing device, a base member, a shoe support pivotally mounted at its forward end to the base member, an adjustable shank support pivoted to the rear end of said shoe support, a yoke the ends of which are pivoted to the sides of said support, a last having an adjustable shank portion for insertion within a shoe upon said support, and means cooperative with the yoke for causing pressure against said last.

2. In a device for cementing shoe soles to shoes, the combination of a base member, a shoe support supported pivotally at one end of said base member, a shank support pivotally mounted to the rear of said shoe support and adjustable to conform to the shape of the shank of a shoe being repaired, a last for insertion within a shoe upon the support, an adjustable shank tread pivoted to one end of said last, a yoke pivoted to the sides of said base member and means cooperative with said yoke for applying pressure upon said last and shank tread against said shoe support whereby said pressure would be distributed evenly throughout a shoe sole interposed between said elements.

3. In a device for cementing shoe soles to shoes, a base member, a rocker beam at the rear thereof, a shoe support pivotally supported adjacent its forward end to the base member and resiliently supported adjacent its rear end, a shank support pivoted to said shoe support and rockable on said rocker beam, an adjustable last for insertion within a shoe upon said support, and means for causing downward pressure upon said last.
